HEATING SYSTEM.

T 0 all whom it may concern:

Be it known that I, THOMAS M. OFFUTT, a citizen of the United States, residing at Connersville, in the county of Fayette and State of Indiana, have invented new and useful Improvements in Heating Systems, of which the following is a specification.

This invention relates to a system of heating, the principal object of the invention being to provide a chamber, the walls of which are formed so as to prevent the radiation of heat and which is adapted to contain a heater with means for conveying the heat generated in the chamber to the point of use.

Another object of the invention is to pro vide means for causing the circulation of air from the building to be heated through said chamber.

While the apparatus is mainly designed for heating purposes it will of course be understood that by substituting a cooling device in the chamber for the heating device the system can be used for cooling the building or the system can be used for fumigating the building by placing a fumigating apparatus in the chamber and causing the vapors generated thereby to be circulated through the building by the circulating de- VlCe.

Still another object of the invention is to provide heat retaining means within the chamber after being once heated and retaining the heat for a long time so thatthe consumption of fuel is reduced to a minimum while securing the maximum effect from the fuel consumed.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describingmy invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a diagrammatic sectional view of the system.

Fig. 2 is a horizontal cross section on line 2--2 of Fig. 1.

Fig. 3 is a section on line 33 of Fig. 1 showing the grates for supporting the heat retaining material, above the heat generating cham r.-

being of cylindrical form but it will of course be understood that it may be made of and desired shape. The body 1 has its outer wall 3 formed of cement or thelike with a lining a of heat non-conducting material on its interior face. An interior wall 5, built of hollow tile set on end, is concentrically arranged within the space formed by the wall 3, the space between the two walls form ing an air chamber 6. The vertical channels formed by the spaces in the hollow tiles are filled with sand and gravel or the like as indicated at 7.

The dome 2 forms a continuation of the wall 3 and may be formed integral therewith or may be formed separate and suitably secured to said wall. This dome may be formed of cement or any other desired material and it is provided with an interior lining 8 of heat nonconducting material.

Grates 9 are placed across the top of the body to separate the body from the dome. These grates rest upon a ledge 10 formed by a part of the wall 3 and upon the wall 5. The drawing shows four of these grates, though it will be understood that any number may be used. These grates permit the air to pass from the space 6 and the chamber 11 into chamber 13, formed by the dome.

A layer 12 of heat retaining material, such as broken rock and the like, is placed on the grates, the said layer being of any desired thickness to suit the purpose in view but this layer must not entirely fill the chamber formed by the dome as it must leave the air chamber 13 at the upper part of the dome.

The chamber 11 is adapted to contain any suitable form of heat generating means, such as the furnace 14, fuel being supplied to said furnace through the coal chute 15 which passes through the walls of the body and is provided with a suitable door 16. The smoke pipe 17 of this furnace passes upwardly through the dome and is connected with the chimney of the building. One or more pipes 18 connect the air chamber 13 of the dome to the room or rooms to be heated. These pipes being provided with suitable dampers 19.

The means for causing the circulation of the air from the rooms through the chambers in the housing comprises any suitable form of blower, indicated at 30, and connected with the chamber 11 by the pipe 21 and with the building by the suction pipe This blower or suction producing de ice may be in the form of an electrically driven fan. When this apparatus is working the air is drawn from the room through the suction pipe 22 and is forced into the chamber 11 through pipe 21. The air in said chamher will be heated by the furnace and will pass from this chamber through the layer 12 into the chamber 13 in the dome and from this chamber 13 will pass back to the rooms through the pipes 18. The heated air pass ing through the layer 12 will highly heat the same and this layer will impart its heat to the air passing through the same when the fire in the furnace is low. In this way when the layer 12 and the wall 5 of the apparatus have become highly heated the furnace may be closed so as to reduce the consumption of coal and rely upon the heated walls and the layer 12 to heat the air passing through the'apparatus. As the heat within the apparatus cannot escape, except by imparting its heat to the air passing through.

the same, the apparatus will work with the minimum amount of fuel so that the maximum amount of heat is gained with but little consumption of fuel and with the least amount of attention on the part of the op erator. V r

It will thus be seen that the housing is a non-conductor of heat and is dust and dirt proof as well as airtight. The lining will prevent the heat from affecting the cement walls.

.Iprefer to place the end of the suction pipe in the floor or adjacent the floor and to place the outlet ends of the heat delivering pipes 18 in the walls adjacent the floor. It will of course be understood, however, that I do not wish to be limited to this ar" rangement. I also prefer to use a folding hood B on each register for the l1eatdelivering pipes, this hood being arranged to direct the heated air downwardly upon the floor. When not in use the hood can be folded back out of the way. This folding hood can also be used in registers placed in the floor.

It will of course be understood that the ap- V paratus can work without-the blower by tion thatthe advantages and norel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of'the several parts, provided that such changes fall within the scope of the appended claims.

. What I claim is 1- l. The herein described system comprising a housing including a body and a top, a lining of heat non-conducting material on the interior wall of said housing, an interior wall spaced from the body of the housing and forming a chamber etween itseif and said body, a grate separating the body of the housing from the top and resting upon the said interior wall, a layer of heat retaining material on said grate, a pipe connecting the interior of the top with the room to be heated, meanswithin the space formed bythe interiorwall for changing the temperature of the air therein and'means for introducing air into said space. 7

2. The herein described system comprising a housing formed with. a cylindrical body and a dome-shaped top,'a' lining of heat non-conducting material on the interior wallof said housing, an interior wall formed of hollow tile spaced from the cylindrical body, the spaces within the tiles being filled with heat retaining material, a

grate separating the cylindrical body from the dome-shaped top and resting upon the tile wall,heat-retaining material located on said grate, apipe connecting the interior of the dome-shaped top with a room, a heating device within the space formed by the interior wall, a suction device and pipes connecting the same with the interior of the housing and with the room.

In testimony whereof I afiix my signature.

THOMAS M. OFFUTT.
